Which DME fix is located at SQS 023023?

• A. Barne
• B. Deske
• C. Ubaby (Not an Intersection)
• D. Dinky (Used in Nonradar)

Answer: (C)

Understanding how DME fixes are defined helps here: some fixes come from the crossing of two radials (intersections), while others are defined solely by a DME distance from a single navaid. The notation SQS 023023 points to a fix measured from the SQS VORTAC/DME by a specific DME distance rather than an intersection of radials. Ubaby is defined as a DME fix that is not an intersection—i.e., it exists at that DME distance from SQS without requiring two radials to meet. That’s why Ubaby is the correct fix for SQS 023023. The other names are typically intersections or have special uses (for example, some may be associated with nonradar procedures), so they wouldn’t be the DME fix defined solely by the single DME reading from SQS.
